Did a search, didn't find anything. My car came with H&R springs installed. It's too low for me, I'm getting some pads to raise it some. But I'm curious how the Sportline springs compare with the H&R springs, and if it would be worthwhile to get the Sportline springs? Whichever I get, I will use with Koni shocks. Right now it has stock shocks, which is a poor combo with lowered springs.
